Description

Technical Field

[0001] This application relates to the field of building power distribution equipment technology, and in particular to a portable mobile device for a mobile switch box. Background Technology

[0002] On construction sites, mobile switch boxes (also known as portable switch boxes) are indispensable key equipment in temporary power supply systems. Their core purpose is to provide safe and convenient power distribution for mobile electrical equipment (such as handheld power tools and small machinery) on the construction site, as well as to control the start and stop of each piece of equipment, while also protecting personnel and equipment.

[0003] In traditional construction methods, workers carry the mobile switch box to different work sites for installation, supplying power to mobile electrical equipment on the construction site. However, when the temporary power supply distance at the construction site is too far, workers need to carry both the mobile switch box and the wiring cable; the whole process is time-consuming and labor-intensive, and can easily damage the cable. Summary of the Invention

[0004] To facilitate the movement of switch boxes by staff, this application provides a portable mobile device for mobile switch boxes.

[0005] This application provides a portable mobile device for a mobile switch box, which adopts the following technical solution:

[0006] A portable mobile device for a mobile switch box includes a mobile frame, a cable winder, and a switch box body. The mobile frame includes a support frame, shock-absorbing rollers, and a telescopic rod. The shock-absorbing rollers are fixed to the bottom of the support frame, and the telescopic rod is fixed to the support frame. The switch box body is detachably mounted on the support frame, and the cable winder is disposed on the support frame for winding cables.

[0007] By adopting the above technical solution, the switch box body is placed on the support frame, so that the staff can quickly move the switch box body to the construction site where electricity is needed; and the cable winder on the support frame can quickly store the cable, saving time and effort while reducing the occurrence of cable tangling, dragging and damage.

[0008] Optionally, the supporting frame includes a first supporting frame body, a second supporting frame body, and a fixing member. The ends of the first supporting frame body and the second supporting frame body are rotatably connected by a pivot. The two ends of the fixing member are detachably connected to the first supporting frame body and the second supporting frame body, respectively. The first supporting frame body is horizontally arranged, and the second supporting frame body is vertically arranged. The first supporting frame body has a through hole for the bottom support leg of the switch box body to pass through. The switch box body is arranged on the first supporting frame body, and the winding device and the telescopic pull rod are arranged on the second supporting frame body.

[0009] By adopting the above technical solution, the first and second load-bearing frames can be rotated and folded for storage, thereby reducing the storage space of the load-bearing frames and making it easier for staff to carry the load-bearing frames.

[0010] Optionally, the shock-absorbing roller is disposed at the bottom of the second bearing frame, and the bearing frame rotates around the shock-absorbing roller; a support rod is provided at the bottom of the first bearing frame, and the support rod is disposed on the side of the first bearing frame away from the second bearing frame; the plane where the bottom of the support rod and the bottom of the shock-absorbing roller are located is parallel to the first bearing frame.

[0011] By adopting the above technical solution and setting a support rod at the bottom of the first load-bearing frame, the stability of the portable mobile device can be improved.

[0012] Optionally, a second vibration damping component is also included. The second vibration damping component includes a plurality of second vibration damping pads, which are spaced apart on the second supporting frame. The second vibration damping pads are used to abut against the switch box body and to support the switch box body.

[0013] By adopting the above technical solution, and by setting a second vibration damping pad between the second supporting frame and the switch box body, the vibration amplitude of the switch box body can be reduced when the staff drags the portable mobile device, thereby reducing the risk of damage to the internal electrical components of the switch box body due to vibration.

[0014] Optionally, it also includes a first vibration damping component, which includes a mounting cylinder and a first vibration damping pad; the first vibration damping pad is disposed on the first bearing frame and is used to support the switch box body; the mounting cylinder is fixed to the bottom of the first bearing frame, the number of mounting cylinders is consistent with the number of support legs, and the mounting cylinder is provided with a channel for the support legs of the switch box body to be inserted.

[0015] By adopting the above technical solution, the support legs of the switch box body are inserted into the mounting cylinder, thereby using the mounting cylinder to constrain the horizontal displacement and vibration of the switch box body, further reducing the risk of damage to the internal electrical components of the switch box body.

[0016] Optionally, the first vibration damping assembly further includes a lifting component, a first spring, a first slide rail, a first slider, a connecting rope, a second spring, and a third vibration damping pad; the lifting component includes a lifting component body and an ear plate, the lifting component body is disposed in the mounting cylinder, the side wall of the mounting cylinder has an elongated guide hole for the ear plate to pass through, the first spring is disposed between the lifting component body and the bottom wall of the mounting cylinder, the first slide rail is disposed on the first bearing frame, the first slider is slidably connected to the first slide rail, and the third vibration damping pad is disposed on the side of the first slider near the switch box body, and the third vibration damping pad is disposed opposite to the first vibration damping assembly. Vibration damping pads are symmetrically arranged on both sides of the switch box body. The connecting rope is used to connect the first slider and the ear plate. The end of the first slide rail is provided with a guide wheel for the connecting rope to be wound. One end of the second spring is connected to the first bearing frame, and the other end of the second spring is connected to the first slider. The second spring forces the first slider away from the switch box body. When the support leg of the switch box body is inserted into the mounting cylinder, the support leg abuts against the lifting member. The support leg forces the lifting member to move downward. The lifting member pulls the first slider closer to the switch box body, so that the three vibration damping pads clamp the switch box body.

[0017] By adopting the above technical solution, when workers drag the portable mobile device on uneven road surfaces, the switch box body is held in place by the relatively set third vibration damping pad; thus, the vibration amplitude of the switch box body can be further reduced, thereby further reducing the risk of damage to the internal electrical components of the switch box body due to vibration, and improving the safety of electricity use at construction sites.

[0018] Optionally, a limiting component is also included, comprising a limiting cylinder and a limiting ball; the limiting cylinder is horizontally disposed on the outer periphery of the mounting cylinder, and the limiting ball is disposed within the limiting cylinder; the bottom of the limiting cylinder is provided with a guide surface, and the distance from the guide surface to the central axis of the limiting cylinder decreases along the direction away from the mounting cylinder; the guide surface is used to prevent the limiting ball from moving to the opening of the limiting cylinder; the opening area of ​​the limiting cylinder is smaller than the projected area of ​​the limiting ball; the mounting cylinder is provided with a communicating hole at the opening of the limiting cylinder; the support leg is provided with a limiting hole for the limiting ball to be inserted; when the supporting frame tilts and moves, the limiting ball is inserted into the limiting hole via the guide surface of the mounting cylinder.

[0019] By adopting the above technical solution, when the portable mobile device walks on uneven road surfaces, the limiting component improves the connection strength and stability between the switch box body and the supporting frame, thereby reducing the vibration of the switch box body and further reducing the risk of damage to the internal electrical components of the switch box body.

[0020] Optionally, the limiting component further includes a first magnetic element and a buffer pad. The first magnetic element is disposed at the bottom of the limiting cylinder, and the buffer pad covers the first magnetic element. The first magnetic element has an attractive force on the limiting ball so that the limiting ball abuts against the buffer pad. The surface of the limiting ball is provided with a plurality of limiting protrusions, and the plurality of limiting protrusions are spaced apart on the outer peripheral surface of the limiting ball.

[0021] By adopting the above technical solution, when the support rod in the portable mobile device is in contact with the ground, that is, when the switch box body is set vertically, the first magnetic component has an attractive force on the limiting ball, so that the limiting ball is fixed on the buffer pad, thereby restricting the movement of the limiting ball.

[0022] Optionally, the limiting component further includes a second magnetic element disposed on the outer periphery of the mounting cylinder and disposed opposite to the limiting cylinder; the second magnetic element has an attractive force on the limiting ball to force the limiting ball to be opened in the limiting hole of the support leg.

[0023] By adopting the above technical solution, the attraction of the second magnetic component to the limiting ball can be used to improve the stability of the limiting ball in the connecting hole of the mounting cylinder and the limiting hole of the support leg.

[0024] Optionally, the second magnetic component includes a mounting housing, a battery, an electromagnet, a circuit, a spring, a suspension rope, and a counterweight disposed within the mounting housing; the electromagnet is disposed on the side of the second magnetic component near the limiting ball, the battery is connected to the electromagnet through the circuit, the spring is disposed on the circuit, and the spring is used to control the on / off state of the circuit; the counterweight is suspended within the mounting housing by the suspension rope; when the movable frame is tilted and dragged, the counterweight moves to compress the spring, thereby connecting the circuit, and the electromagnet generates a magnetic field to attract the limiting ball; when the movable frame is vertically positioned, the counterweight separates from the spring under the action of gravity, and the circuit is disconnected.

[0025] By adopting the above technical solution, when the frame is tilted and dragged, the circuit in the second magnetic component is connected, causing the electromagnet to generate a large magnetic field, which makes the second magnetic component have a greater attractive force on the limiting ball, thereby improving the stability of the limiting ball in the connecting hole of the mounting cylinder and the limiting hole of the support leg.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Place the switch box body on the support frame so that workers can quickly move the switch box body to the construction site where electricity is needed; and the cable winder on the support frame can quickly store the cable, saving time and effort while reducing cable tangling, dragging and damage.

[0028] 2. When workers drag the portable mobile device on uneven road surfaces, the third vibration damping pad, which is positioned opposite to the switch box body, clamps the switch box body and exerts a large compressive force on it. This further reduces the vibration amplitude of the switch box body, thereby reducing the risk of damage to the internal electrical components due to vibration and improving the safety of electricity use at construction sites.

[0029] 3. When the portable mobile device travels on uneven surfaces, the limiting component improves the connection strength and stability between the switch box body and the supporting frame, thereby reducing the vibration of the switch box body and further reducing the risk of damage to the internal electrical components of the switch box body.

[0042] The following is in conjunction with the appendix Figure 1 Section 11 provides further details regarding this application.

[0043] This application discloses a portable mobile device for a mobile switch box. (See also...) Figure 1 and Figure 2 The portable mobile device of the mobile switch box includes a mobile frame 1, a winding device 2, and a switch box body 3.

[0044] Reference Figure 1 and Figure 3 The mobile frame 1 includes a load-bearing frame 11, shock-absorbing rollers 12, and a telescopic rod 13. The load-bearing frame 11 includes a first load-bearing frame body 111, a second load-bearing frame body 112, and a fixing member 113. The first load-bearing frame body 111 is horizontally arranged, and the second load-bearing frame body 112 is vertically arranged. The ends of the first load-bearing frame body 111 and the second load-bearing frame body 112 are rotatably connected via a pivot. Both ends of the fixing member 113 are detachably connected to the first load-bearing frame body 111 and the second load-bearing frame body 112, respectively. In this embodiment, the fixing member 113 is a flat rod, and both ends of the fixing member 113 are detachably connected to the first load-bearing frame body 111 and the second load-bearing frame body 112 via bolts.

[0045] Reference Figure 1 and Figure 3The shock-absorbing roller 12 is fixed to the bottom of the second load-bearing frame 112. A support rod 14 is provided at the bottom of the first load-bearing frame 111, located on the side of the first load-bearing frame 111 away from the second load-bearing frame 112. The bottom of the support rod 14 and the bottom of the shock-absorbing roller 12 are on the same plane, and this plane is parallel to the first load-bearing frame 111. A telescopic rod 13 is fixed to the side of the second load-bearing frame 112 away from the first frame. Workers can move the load-bearing frame 11 on the ground by pulling the telescopic rod 13. When the worker rotates the telescopic rod 13, the load-bearing frame 11 rotates around the shock-absorbing roller 12, and the support rod 14 at the bottom of the first load-bearing frame 111 separates from the ground. Workers can then move the load-bearing frame 11 on the ground by pulling the telescopic rod 13. In this embodiment, both the first load-bearing frame 111 and the second load-bearing frame 112 are made of aluminum alloy to ensure a lightweight overall structure capable of supporting a large weight.

[0046] Reference Figure 1 and Figure 2 The switch box body 3 is detachably mounted on the support frame 11. The cable winder 2 is mounted on the support frame 11 and is used to wind up the cable. In this embodiment, the first support frame 111 has a through hole for the bottom support leg 31 of the switch box body 3 to pass through, and the switch box body 3 is directly mounted on the first support frame 111. The cable winder 2 is located on the side of the second support frame 112 away from the first support frame 111 and is used to wind up the cable. When the operator rotates the support frame 11, causing the support rod 14 to separate from the ground, the bottom of the switch box body 3 abuts against the first support frame 111, and the side wall of the switch box body 3 abuts against the second support frame 112.

[0047] In this embodiment, a grounding wire device is provided on the support frame. This grounding wire device can be directly and fixedly connected to the PE busbar inside the mobile switch box, thereby grounding the mobile switch box and improving electrical safety. Simultaneously, the mobile switch box can be directly placed on the vehicle frame, simplifying the operation steps for staff. The grounding wire device can be an electrostatic grounding clamp.

[0048] The implementation principle of the portable mobile device for a mobile switch box in this application embodiment is as follows:

[0049] Reference Figure 1 and Figure 2 Workers place the switch box body 3 on the support frame so that they can quickly move the switch box body 3 to the construction site where electricity is needed; and the cable winder 2 on the support frame can quickly store the cable, saving time and effort while reducing cable tangling, dragging and damage.

[0050] Reference Figure 1 and Figure 2 By setting a support rod 14 at the bottom of the first support frame 111, the stability of the portable mobile device is improved; thereby, when the switch box body 3 is working, the risk of the portable mobile device moving can be reduced and the electrical safety can be improved.

[0051] Reference Figure 1 and Figure 2 The first and second load-bearing frames can be rotated and folded for storage, thereby reducing the storage space required for the load-bearing frames and making it easier for staff to carry them.

[0052] Example 2

[0053] The difference between Example 2 and Example 1 is as follows:

[0054] Reference Figure 4 and Figure 5 The portable mobile device of the mobile switch box also includes a first vibration damping pad 4, a first vibration damping component 5, and a second vibration damping component 6.

[0055] Reference Figure 4 and Figure 5 The first vibration damping pad 4 is disposed on the first bearing frame 111 and is used to support the switch box body 3.

[0056] Reference Figure 4 and Figure 6 In this embodiment, the first vibration damping component 5 is disposed on the first supporting frame 111, and there are four first vibration damping components 5, which are disposed in the four corner areas of the switch box body 3.

[0057] Reference Figure 6 and Figure 7The first vibration damping component 5 includes a mounting cylinder 51, a lifting member 52, a first spring 53, a first slide rail 54, a first slider 55, a connecting rope 56, a second spring 57, and a third vibration damping pad 58. The mounting cylinder 51 is fixed to the bottom of the first supporting frame 111. The number of mounting cylinders 51 corresponds to the number of support legs 31. The mounting cylinder 51 has a channel for the support legs 31 of the switch box body 3 to be inserted. The lifting member 52 includes a lifting member body 521 and an ear plate 522. The lifting member body 521 is disposed inside the mounting cylinder 51. The side wall of the mounting cylinder 51 has an elongated guide hole 511 for the ear plate 522 to pass through. The first spring 53 is disposed between the lifting member body 521 and the bottom wall of the mounting cylinder 51. The first slide rail 54 is disposed on the first supporting frame 111. The first slider 55 is slidably connected to the first slide rail 54 and is used to move closer to or further away from the switch box body 3. The third damping pad 58 is disposed on the side of the first slider 55 near the switch box body 3. The third damping pads 58 of the first damping assembly 5 are symmetrically disposed on both sides of the switch box body 3. The connecting rope 56 is used to connect the first slider 55 and the ear plate 522, and the end of the first slide rail 54 is provided with a guide wheel 59 for the connecting rope 56 to be wound. One end of the second spring 57 is connected to the first slide rail 54, and the other end of the second spring 57 is connected to the first slider 55. The second spring 57 forces the first slider 55 away from the switch box body 3.

[0058] Reference Figure 6 and Figure 7 When the support leg 31 of the switch box body 3 is inserted into the mounting cylinder 51, the support leg 31 abuts against the lifting member 52. The support leg 31 forces the lifting member 52 to move downward. The lifting member 52 pulls the slider closer to the switch box body 3, so that the four symmetrically arranged third damping pads 58 clamp the switch box body 3.

[0059] Reference Figure 4 and Figure 5 The second vibration damping component 6 includes a plurality of second vibration damping pads 61, which are spaced apart on the second supporting frame 112. The second vibration damping pads 61 are used to abut against the switch box body 3 and to support the switch box body 3. In this embodiment, when the support leg 31 at the bottom of the switch box body 3 is inserted into the mounting cylinder 51, the side wall of the switch box body 3 will squeeze the second vibration damping pads 61 to ensure that the second vibration damping pads 61 have a supporting effect on the switch box body 3.

[0060] The implementation principle of the portable mobile device for a mobile switch box in this application embodiment is as follows:

[0061] When workers drag the portable mobile device on uneven surfaces, the device swings significantly in the vertical direction.

[0062] In this embodiment, since a first vibration damping pad 4 is provided between the switch box body 3 and the first supporting frame 111, and a second vibration damping pad 61 is provided between the switch box body 3 and the second supporting frame 112, the first vibration damping pad 4 and the second vibration damping pad 61 can reduce the vibration amplitude of the switch box body 3 when the staff drags the portable mobile device, thereby reducing the risk of damage to the internal electrical components of the switch box body 3 due to vibration.

[0063] Furthermore, when the operator places the switch box body 3 on the first supporting frame 111, the support leg 31 of the switch box body 3 is inserted into the mounting cylinder 51. The support leg 31 abuts against the lifting member 52, forcing the lifting member 52 to compress the first spring 53 downwards. The lifting member 52 pulls the first slider 55 through the connecting rope 56, causing the first slider 55 to carry the third vibration damping pad 58 close to the switch box body 3. Subsequently, the third vibration damping pad 58 is squeezed and deformed against the switch box body 3, thereby achieving the purpose of the third vibration damping pad 58, which is relatively set on both sides of the switch box body 3, squeezing the switch box body 3.

[0064] Therefore, when workers drag the portable mobile device on uneven road surfaces, the third vibration damping pad 58, which is positioned opposite each other, holds the switch box body 3 and exerts a large compressive force on the switch box body 3. This can further reduce the vibration amplitude of the switch box body 3, thereby further reducing the risk of damage to the internal electrical components of the switch box body 3 due to vibration and improving the safety of electricity use at construction sites.

[0065] Example 3

[0066] The difference between Example 3 and Example 2 is as follows:

[0067] Reference Figure 8 The portable mobile device of the mobile switch box also includes a limiting component 7; in this embodiment, there are two limiting components 7, and the two limiting components 7 are located on the side of the switch box body 3 away from the second supporting frame 112.

[0068] Reference Figure 9 The limiting component 7 includes a limiting cylinder 71, a limiting ball 72, a first magnetic element 73, a buffer pad 74, and a second magnetic element 75.

[0069] Reference Figure 9A limiting cylinder 71 is horizontally disposed on the outer periphery of the mounting cylinder 51, and a limiting ball 72 is disposed inside the limiting cylinder 71. A first magnetic element 73 is disposed at the bottom of the limiting cylinder 71, and a buffer pad 74 covers the first magnetic element 73. The limiting ball 72 is a steel ball, and the first magnetic element 73 has an attractive force on the limiting ball 72, so that the limiting ball 72 abuts against the buffer pad 74. In this embodiment, the first magnetic element 73 is a magnet; the buffer pad 74 is a porous rubber pad to protect the first magnetic element 73.

[0070] Reference Figure 9 The opening of the limiting cylinder 71 is provided with a guide surface 712. Along the direction away from the mounting cylinder 51, the distance from the guide surface 712 to the central axis of the limiting cylinder 71 decreases. The guide surface 712 is used to prevent the limiting ball 72 from moving to the opening of the limiting cylinder 71. The opening area of ​​the limiting cylinder 71 is smaller than the projected area of ​​the limiting ball 72. The mounting cylinder 51 is provided with a connecting hole 512 at the opening of the limiting cylinder 71; the support leg 31 is provided with a limiting hole 311 for the insertion of the limiting ball 72. When the supporting frame 11 is tilted and dragged, the guide surface 712 of the mounting cylinder 51 is tilted downwards, so that the limiting ball 72 is inserted into the limiting hole 311 through the guide surface 712 of the mounting cylinder 51.

[0071] Reference Figure 9 In this embodiment, the surface of the limiting ball 72 is provided with a plurality of limiting protrusions 721, which are spaced apart on the outer peripheral surface of the limiting ball 72. Furthermore, a second magnetic element 75 is disposed on the outer periphery of the mounting cylinder 51, and is disposed opposite to the limiting cylinder 71; the second magnetic element 75 has an attractive force on the limiting ball 72, thereby forcing the limiting ball 72 to be formed in the limiting hole 311 of the support leg 31. In this embodiment, the second magnetic element 75 is a magnet.

[0072] The implementation principle of the portable mobile device for a mobile switch box in this application embodiment is as follows:

[0073] Reference Figure 8 and Figure 9 When the support rod 14 in the portable mobile device comes into contact with the ground, that is, when the switch box body 3 is set vertically, the first magnetic element 73 has an attractive force on the limiting ball 72, so that the limiting ball 72 is fixed on the buffer pad 74, thereby restricting the movement of the limiting ball 72.

[0074] When the operator places the switch box body 3 on the support frame 11, and then holds the telescopic rod 13 and rotates the support frame 11 while dragging the portable mobile device, the guide surface 712 is actually tilted downwards after the support frame 11 rotates. The limiting ball 72 moves through the guide surface 712 to the opening of the limiting cylinder 71, and part of the limiting ball 72 passes through the connecting hole 512 of the mounting cylinder 51 and is locked in the limiting hole 311 of the support leg 31. The attraction of the second magnetic component 75 to the limiting ball 72 can improve the stability of the limiting ball 72 locked in the connecting hole 512 of the mounting cylinder 51 and the limiting hole 311 of the support leg 31.

[0075] Reference Figure 9 The limiting ball 72 has a limiting protrusion 721 on its surface. When the limiting ball 72 is engaged in the connecting hole 512 of the mounting cylinder 51 and the limiting hole 311 of the support leg 31, the risk of the limiting ball 72 falling off can be reduced, thereby improving the connection stability between the switch box body 3 and the bearing frame 11 and reducing the vibration of the switch box body 3 on the bearing frame 11.

[0076] In this embodiment, a limiting ball 72 is inserted between the mounting cylinder 51 and the support leg 31 to improve the connection strength between the support leg 31 and the mounting cylinder 51 in the switch box body 3. Therefore, when the portable mobile device travels on uneven surfaces, the limiting component 72 improves the connection strength and stability between the switch box body 3 and the load-bearing frame 11, reducing vibration of the switch box body 3 and further reducing the risk of damage to the internal electrical components of the switch box body 3.

[0077] Example 4

[0078] The difference between Example 4 and Example 3 is as follows:

[0079] Reference Figure 10 and Figure 11 The second magnetic component 75 includes a mounting housing 751, a battery 752, an electromagnet 753, a circuit 754, a spring 755, a suspension rope 756, and a counterweight 757 disposed within the mounting housing 751.

[0080] Reference Figure 10 and Figure 11 An electromagnet 753 is positioned on the side of the second magnetic component 75 near the limiting ball 72. A battery 752 is connected to the electromagnet 753 via a circuit 754. A spring 755 is positioned on the circuit 754 and is used to control the on / off state of the circuit 754. Under normal conditions, the spring 755 will disconnect the circuit 754.

[0081] Reference Figure 10 and Figure 11The counterweight 757 is suspended inside the mounting housing 751 by a suspension rope 756. When the moving frame is vertically positioned, the counterweight 757 separates from the spring piece 755 under gravity, and the circuit 754 is disconnected. When the moving frame is tilted and dragged, the counterweight 757 moves towards the spring piece to press the spring piece 755, thereby connecting the circuit 754. The electromagnet 753 generates a magnetic field to attract the limiting ball 72. In this embodiment, the counterweight 757 is not ferromagnetic; that is, the electromagnet 753 does not have an attractive force on the counterweight 757, thus causing the counterweight 757 to press the spring piece 755 downward to connect the circuit 754.

[0082] The implementation principle of the portable mobile device for a mobile switch box in this application embodiment is as follows:

[0083] Reference Figure 10 and Figure 11 When the frame is tilted and dragged, the circuit 754 in the second magnetic component 75 is turned on, causing the electromagnet 753 to generate a large magnetic field, which makes the second magnetic component 75 have a strong attraction to the limiting ball 72; thereby, the stability of the limiting ball 72 in the connecting hole 512 of the mounting cylinder 51 and the limiting hole 311 of the support leg 31 can be further improved, and the risk of damage to the electrical components inside the switch box body 3 can be reduced.

[0084] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
